An astronaut has a mass of 60 kg on Earth. The gravity on the Moon is one-sixth of that on Earth. Taking g = 10 m/s² on Earth, what are the astronaut's mass and weight on the Moon?
A child has thin arms and legs, a swollen belly and swelling of the feet (oedema), and his diet is rich in starch but very poor in protein. He is most likely suffering from a deficiency of:
A student records the potential difference (V) across a resistor and the current (I) through it:
V (volt): 2, 4, 6, 8
I (ampere): 0.5, 1.0, 1.5, 2.0
Find the resistance of the resistor and the power consumed when V = 8 V.
